Abstract
This paper presents an application of the X-ray absorption technique for
monitoring hydration and setting processes in cementitious composites. The
method, which is a relatively new approach in concrete research, is based on the
measurement of attenuation of a finely collimated beam of X-rays by a sample.
The absorption of X-rays by sample is proportional to the material density.
Changes of density in a function of time can be related to the absorption and
moisture transport within porous media. Although interpretation of the results
may be very problematic, chemical and physical reactions associated with
hydration may be qualitatively analysed by this technique. This paper is focused
on a setting process of cement mortars modified by superabsorbent polymers.
Keywords: X-ray absorption, hydration process, cementitious materials,
superabsorbent polymers.
